Struct DefaultHasher

pub struct DefaultHasher(/* private fields */);

The default Hasher used by RandomState.

The internal algorithm is not specified, and so it and its hashes should not be relied upon over releases.

Implementations

Source

impl DefaultHasher

1.13.0Source

pub fn new() -> DefaultHasher

Creates a new DefaultHasher.

This hasher is not guaranteed to be the same as all other DefaultHasher instances, but is the same as all other DefaultHasher instances created through new or default.
